For ultra-discreet sound all around the home, or partnered with the Monitor Audio Radius 380 sub for explosive stereo, the miraculously small Radius 45 houses a 3" MMP®II mid-bass driver and rear-firing 3/4” C-CAM® tweeter, and has no right to sound as good as it does.


  • 3" MMP®II Driver. All drivers are dedicated and model specific, with each model in the Radius series being designed and voiced individually.

  • 3/4" gold C-CAM® tweeter, rear-firing to enhance sound dispersion characteristics

  • Single through-bolt driver fixing. Provides mechanical de-coupling properties resulting in enhanced mid-band clarity and resolution. Through-bolts also act as rigid cross bracing to give a very solid non-resonant cabinet.

  • Single point ¼"x20TPI wall fixing. Use the optional Monitor Audio speaker mount or any standard wall bracket

  • Optional floor-stand with internal (pre-wired) cable management system
